Is Facebook's Mark Zuckerberg the Best CEO in Tech in 2013?

Here's why Facebook's Mark Zuckerberg may be the best CEO in all of tech this year.

In this video from Monday's Investor Beat, host Chris Hill and Motley Fool tech and telecom bureau chief Evan Niu look at the biggest trends in the tech sector as 2013 comes to a close.

One of the stories that dominated the investing thesis for Facebook(NASDAQ:FB) after its IPO in 2012 were questions of whether or not the company could capitalize on mobile ad revenue. In October 2012, Mark Zuckerberg stated adamantly that the company could indeed make money on mobile despite the naysayers. However, its earnings that quarter showed that mobile ad revenue accounted for only 14% of the company's total advertising revenue. Now, mobile ad revenue accounts for 49% of Facebook's ad revenue, up from $150 million to nearly $900 million, an increase of nearly 500% in a year's time. Evan tells investors why delivering on this promise makes Mark Zuckerberg tech's CEO of the year, and why Facebook on mobile devices now represents a dream opportunity for advertisers.
